Connect the Power Cords
 | Caution - Do not attach power cords to the power supplies on the compute nodes until you have connected the compute nodes to a serial terminal or a terminal emulator (PC or workstation). The compute nodes go into Standby mode and Oracle ILOM on the SP initializes as soon as power cables connect the power supplies to an external power source. System messages might be lost after 60 seconds if a terminal or terminal emulator is not connected to the SER MGT ports before power is applied. |
Note - Oracle ILOM signals a fault if both power supplies on each compute node are not cabled at the same time, because that is a nonredundant condition. Do not be concerned with this fault in this situation.
Note - To guarantee redundancy, connect the power cords to separate and independent power sources.
- Connect the power cords to the separate external AC power sources, and supply power to the external power sources.
- Route the power cords from the separate AC power sources to the rear of the compute nodes and storage array.
-
Ensure that you meet these electrical safety measures before applying power to
the storage array:
-
Provide a suitable power source with electrical overload protection to meet the power supply input voltage range of 100 to 240 VAC, 50 to 60 Hz. The storage arrays are compatible with 100 to 120 VAC or 200 to 240 VAC sources. The power source must not be overloaded by the total number of storage arrays in the rack.
-
Ensure that the power source provides a reliable earth connection for each storage array and the rack.
-
Ensure that the power source is easily accessible because the power cord is the main disconnect device for the storage array.
-
-
For the storage array, plug a power cord into the power connector in each
power supply.

For the compute nodes, connect the power cords to the power supplies.
When the power cords are connected, the SP initializes and the power supply LEDs illuminate. After a few minutes, the SP login prompt is displayed on the terminal device. At this time, the host is not initialized or powered on.
